The coal mining industry has some unique characteristics, that distinguish this industry with other industries: capital intensive, technology-intensive, and has high risk. A workplace accident is one of the risks that has high importance because can cause various losses such as material loss, disruptions to the production process and damages to the environment. MUTU coal company, a company engaged in the coal mining sector in Indonesia, is experiencing an increasing number of workplace accident by 34.7% from 2017 to 2018. The workplace accident caused by various factors from various sources or levels, starting from the level of operators, supervisors, management, and company. Human Factor Analysis and Classification Systems Method for Coal Mines (HFACS-CM) was used in this study to analyze human factors that cause workplace accident, starting from the level of unsafe acts, preconditions for unsafe acts, unsafe leadership, organizational influences, and external environmental factors. Structural Equation Modeling (SEM) was constructed to analyze the relationship between factors affecting workplace accident based on the HFACS-CM model. The result proved that external environmental has a significant impact on unsafe acts, preconditions for unsafe acts have a significant impact on unsafe acts, organizational influences have a significant impact on unsafe leadership, unsafe leadership has a significant effect on the preconditions for unsafe acts, and external environment is significantly related to organizational influences.

Most crimes being committed around the streets are left unreported, despite the presence of various acts enacted by the government. There is also an issue of the police not being able to respond on time as there are lots of people who may be reporting, and not every emergency may be attended. With that, the researchers have decided to devise a quick emergency response system that can help citizens of Taguig City, Philippines send an emergency call to the police fast and record it automatically. A research on related tools and frameworks has been conducted to support the system. It was tested by the citizens of Taguig to assess if the system has improved the emergency response times. Based on the results, a large percentage of citizens believed that the system created is much more intuitive compare to calling the policemen via phone.

Multi-projects are quite common in industries, especially in made-to-order enterprises. These projects usually require limited local or global resources distributed and controlled by different departments. The scheduling problem for this kind of multi-projects is known as distributed resource constrained multi-projects scheduling problem (DRCMPSP). It is difficult to resolve the conflict of interest between different departments during scheduling. In this paper, a new hierarchy model using heuristic method based on priority rules for solving the problem. The decision making process is supposed to be hierarchical and decentralized, with one global decision maker and as many local decision makers as the resources managers. The difference between the method proposed and other hierarchical methods is that its decision stages and makers are divided from the department or manager, not from projects. It can achieve the benefit coordination between project managers and resources managers, and thus generate the overall optimal scheduling.

The building is identified as one of the largest electricity user. The reduction of energy consumption in the building sector has the considerable opportunity and the significant impact on the growth of energy demand, consequently, it would reduce the production of the carbon emissions globally. This paper analyzes the real-time monitoring result of power and energy consumption for 3 building sample in Andalas University, Indonesia, in order to find energy saving opportunities. In this study a real-time energy monitoring system has been developed, hence their results were recorded in every five minutes for each building. The data recorded was analyzed and plotted to obtain the energy patterns consumed daily during 3 months and the pattern of load power weekly. The opportunity of the energy savings can be analyzed by reviewing the relationship between the pattern of load power weekly and energy consumed patterns daily. In meantime, the activities in the building/rooms related to consume electrical energy based on the working time, lecturing schedules, academic calendar and field observations toward energy user and load behaviors. The analysis results have obtained opportunities for energy savings the outside of working hours in the building of engineering faculty, lecturing, and central library, respectively: 21.06%, 20.17%, and 9.85%. Meanwhile, during working hours, the opportunities for energy savings are still qualitative results. A short-term solution in implementing energy saving opportunities could be done through the management policy.

Traveling Salesman Problem (TSP) is an NP-hard optimization problem that can be solved by a heuristic composite algorithm. A composite algorithm is a heuristic optimization model that combine tour construction algorithm and tour improvement algorithm. Clarke Wright Savings heuristic is one of the best methods that produce a good initial solution, and local search is known to be a successful operator to make an improvement solution. This paper will present a composite algorithm as a preliminary model based on Clarke wright savings and local search K-opt to solve TSP. The experimental result shows that the proposed algorithm can solve a large problem instance of Traveling Salesman Problem up to 85.900 points, with competitive results, small variations of computing time for 30 problem instances, and relatively short computing time.

Analytic Hierarchy Process (AHP) method provides weight for each criterion and sub-criterion that will be divided into two segmentations constructed by the interviewees. Technique for Order of Reference by Similarity to Ideal Solution (TOPSIS) method provides assessment for each rest area supplier and sequence for each segment. These two methods are a great tool to make better qualitative decision. Therefore, combining these methods would create a better procurement decision in Indonesian toll road rest areas. Green Public Procurement (GPP) is a process that could help public authorities in designing products, services, and processes with fewer and more compact environmental effects. GPP concept are expected to uptake the quality of the vendors sustainably. Indonesia's government is still evaluating and improving logistic infrastructure by building various infrastructure, with building Trans-Java toll road, with total distance more than 1000 kilometers. This toll road will be added with 61 rest areas along the road. Rest areas in Indonesia's toll road are divided into three types depending on the needs of themselves. It is needed to improve the criteria of the rest area's vendors and assessment of the existing vendors. Criteria selection using AHP method and assessment and segmentation using TOPSIS method. Final results from the research are the largest weight from the criteria and sub criteria also segmentation and improvement for supplier. This research will give impact to better environment, such as pollution reduction and conform Indonesia's regulation on green procurement.
层次分析法(AHP)方法为每个标准和子标准提供权重，这些子标准将被分为由受访者构建的两个部分。TOPSIS (Similarity to Ideal Solution)方法提供了对每个休息区供应商和每个片段的顺序的评估。这两种方法是做出更好的定性决策的有力工具。因此，将这些方法结合起来，可以在印尼收费公路休息区制定更好的采购决策。绿色公共采购(GPP)是一个可以帮助政府当局设计产品、服务和流程的过程，对环境的影响更小、更紧凑。GPP概念有望持续吸收供应商的质量。印尼政府仍在评估和改善物流基础设施，通过建设各种基础设施，建设跨爪哇收费公路，总距离超过1000公里。这条收费公路沿线将增设61个休息区。印尼收费公路上的休息区根据自己的需要分为三种类型。需要改进休息区供应商的标准和对现有供应商的评估。采用AHP法进行标准选择，采用TOPSIS法进行评价和分割。研究的最终结果是来自标准和子标准的最大权重，以及对供应商的细分和改进。本研究将对更好的环境产生影响，如减少污染，并符合印度尼西亚的绿色采购法规。

The sector of small industrial companies has a problem with not being able to satisfy total market demand, mainly due to factories not capitalizing on their production capacity. Consequently, a method to solve downtime related problems has been proposed, which consists of applying 5S to reduce dead time stemming from disorder and uncleanliness, while simultaneously applying value stream mapping (VSM) to find the most efficient method to conduct processes. In conclusion, by implementing these tools in this manner, it was proven that businesses in this sector could operate with up to 73% efficiency.

Analytic Hierarchy Process (AHP) is often used for making decision with multiple criteria. It helps to breakdown complicated problem into a smaller, less-complicated problem. The use of AHP allows decision maker to see what aspects are more important in the decision making process. While Goal Programming (GP) is used to help calculate the optimum option out of the desired. GP is used in this research because using AHP alone will be too subjective. Combining the two method will be a new approach in selecting new highway location in Indonesia and will increase the accuracy of decision making. This research is focused on making decision to select a new rest area location. Location selection is a crucial decision for any company that may be difficult to solve because of the existence of conflicting factors. In the highway industry, rest area location selection involves several quantitative and qualitative factors such as topography, infrastructure, government policy, social environment and human factors. AHP was used to calculate the relative importance of each criteria and sub-criteria in accordance with the opinions of experts. From this study, we know that human factors and government policy play the most important role in the location selection. The result of this calculation is the selection of two location alternatives for the next rest area. The impact from this research will be beneficial for the safety of road user and will help decrease accident rate in highway.

Many countries have implemented Extended producer responsibility (EPR) strategies in terms of packaging waste management. Albeit having the regulations on waste management stated that producers have to take responsibility in managing their product waste, Indonesia, as the second largest contributor of plastic waste to the open ocean, has yet to implement EPR strategies in their plastic packaging waste management policy. To further address this environmental issue, the government of Indonesia formulated National Waste Management Policy and Strategy in 2017, which aims to reduce 30% of waste generation and manage 70% of waste generated in 2025. This study provides a conceptual model of system dynamics, which integrates EPR strategy schemes into the current plastic waste management policy in Indonesia using a causal loop diagram. This valid conceptual model hopefully could support many policy modelers to construct valid system dynamics model to evaluate relevant waste management policies in the future.

This action research aims to reduce waste of powder color in powder coating process of air conditioner parts in a case company. Six-sigma methodology together with contemporary quality improvement tools and techniques such as seven basic quality control tools were applied. More workpieces were arranged on hanging hooks to increase spraying areas. Spraying gun movement levels were reset to fit with the size of individual workpiece. Speed of spraying gun movement and air pressure rate of the spraying gun were tested for more suitable parameters. It was found that waste of powder color significantly decreased without negative effect of higher defect rate. Production volume increase due to shorter cycle time, too.
